Hello ALL:))))

   

this is my first post and MYFIRST  PROJEcT ,as well,

   

I have got raw serial data from sanyo LC7981 LCD controller

   

FLM:  A pulse on this line resets the frame position to top-left
CL1 (LP): This triggers an increment in the line counter (Y position)
CL2 (Clock): This shifts one pixel in through D and increments the pixel counter (X position)
D (Data): The incoming data bits, one bit per display pixel

   

Is it a SPI interface ?

   

which wAs connected to graphic (240x64) serial LCD 

   

but with EL backlight and not looks nice

   

I would like to build converter serial to parallel graphic (240x64) LCD  using psoc 5lp 

   

if someone can help newbie person , please.

   

how to so it?

   

which component can I use?

   

or any example project which can help me welcome!!!

   

thank Tou,

   

marek

   

Any question please ask , I am realy happy to continue that project

Oh, and it's 2MHz clock frequency.

CL1 and 2 are not a SPI interface, they are dot clock and output

   

of an osc circuit in controller. See block diagram in dataheet. The

   

basic interface is byte parallel, and EMIF component probably most

   

appropriate.

   

 

   

This project might be useful to look at, although it was done with PSOC

   

4 which does not have EMIF component. But was doen with a custom component

   

which you have the option of doing.
